Saturday's quake was shallow, occurring at a depth of 10 kilometers (six miles). Shallow quakes generally tend to be more damaging than deeper quakes. Seismic waves from deep quakes have to travel farther to the surface, losing energy along the way, while the shaking from shallow quakes is more intense.

Recent earthquakes in the area have caused secondary hazards such as landslides. The last notable quake in the region was in 2004 and measured 4.7.
